Continuity mistake: As Rhodey and Tony are walking through school and Tony asking why his dad wants this of him, a girl in an orange shirt stumbles and pushes through them, continuing on as she apologizes. First is a view from in front of the boys just before it cuts, and Rhodey’s arms slightly flare out and his eyes close with mouth open as she passes between them, and Tony’s mouth is open. It then cuts to a view from the other angle and suddenly Rhodey is standing almost perfectly still, hands at his side, eyes open and mouth shut. Tony’s mouth is also shut.
